Today, in the competitive global economy, evaluating the financial performance of companies is very important not only for current and potential managers, creditors, and investors but also for companies operating in a sector. Evaluating the financial performance of companies is very important not only for current and potential managers, creditors and investors but also for companies active in a sector. The purpose of this research was to identify and prioritize the key factors affecting the company's financial performance. Therefore, by using the Fuzzy Dematel approach and gathering the opinions of experts with a pairwise comparison questionnaire, the relationship between the indicators affecting the enterprise's financial performance has been discussed. The results showed Asset Management (WCC) has the most Prominence and interaction with other criteria and since $(D_i-R_i)$ is negative for this factor, so this criterion is a net effect. Asset Management (OE) after Asset Management (WCC) has the most interaction with other criteria and since $(D_i-R_i)$ is negative for this factor, so this criterion is a net effect. The income statement is net cause for $(D_i-R_i)$ is positive for this factor.

Geoenergy has a significant effect in optimizing the analysis of mechanical phenomena during drilling, exploration, production and even release of an oil field. Identifying the technological capabilities of geomechanics in Iran's oil and gas industry is effective in improving the exploration and production process. Therefore, the current research has extracted, categorized and interpreted the basic, organizing and inclusive themes using a multi-method qualitative approach (theme analysis and gray Delphi). Therefore, first, semi-structured interviews were conducted with 14 industrial and academic managers and experts, and using the theme analysis approach based on the inductive strategy, technological capabilities in the field of oil and gas geomechanics were identified and categorized into 7 organizing themes and 34 basic themes. . The themes of the organizer include investment capability with 4 basic themes, linking/networking capability with 5 basic themes, learning capability with 6 basic themes, human resources capability with 4 basic themes, management and strategic capability with 7 basic themes, technical and executive capability with 4 themes Basic, complementary capability is formed by 4 basic themes. Then, by doing gray Delphi, these themes were classified into five classes in order of importance. Credibility in senior managers, the existence of a strategic plan and access to sufficient credit resources were of the highest importance.

Technology is one of the most important factors of economic growth and development of countries. Due to the technological gap in developing and less-developed countries, technology transfer has many short-term and long-term benefits. In the meantime, the development of environmental standards as a strategy for technology transfer forces foreign manufacturers to supply new and environmentally friendly technologies. Therefore, the aim of this research is to prioritize technology transfer strategies based on environmental standards. Therefore, based on the survey strategy using the questionnaire of paired comparisons, the opinions of 37 experts were collected. Then, technology transfer strategies based on environmental standards were prioritized using fuzzy hierarchical analysis. the results showed that Compilation of regulations and standards related to the environment with a relative weight of 0.458, the highest weight, implementation of project financial mechanisms with a relative weight of 0.299, imposition of environmental tariffs with a relative weight of 0.242, second and third positions, and finally, formulation and protection of property rights Manavi with a relative weight of 0.083 have taken the fourth place.

New urban planning paradigms have provided a new framework based on sustainable cities for urbanization. Nowadays, a smart solution is submitted by day and these solutions make cities radically change the way they are managed today. According to this view, various dimensions can be offered for a sustainable smart city. To determine the smart sustainable city concept, need to define the dimensions of a specific city are smart and sustainable. So, this study aims to analyze the causal relationships of sustainable smart city dimensions. therefore, a fuzzy DEMATEL solution is developed and presented. The population is 42 urban developers who are chosen reasonably. A pairwise matrices questionnaire was made to compare and match each couple of criteria. A group of experts evaluated the correlation between criteria. Then, the linguistic variables were put into triangular fuzzy numbers and then their opinion about the criteria was collected. After that, the crisp total direct relation matrix, the fuzzy, and the normalized matrix of direct relation were calculated. Findings showed that Policy factors affect all six other factors and are influenced by all the other factors except Environmental factors. Governance factors influence all six other factors and are affected by Policy and Business factors. Economic factors affect all the other factors except Governance factors. Environmental factors are affected by four other factors (Policy, Economic, Governance, Inhabitant). [...]

In many developing countries, faced with the need to promote and strengthen the economy's long-term access to new technology, management know-how in many cases significantly associated with lack of resources, have floundered. Strengthen the local economy with a potential role in the shortage of foreign direct investment on economic growth in these countries is long-term. Therefore, this article tries to account 17 during the period 1990 to 2019 to analyze the impact of developing country foreign direct investment on economic growth in these countries will be discussed.In this study, the effect of labor variables, gross domestic fixed capital formation, the rate of economic openness and foreign direct investment on economic growth is estimated to selected countries.Also, although initially positive effect of FDI on economic growth, but this effect was reversed a year break and have a negative impact on the economy, which could be due to leakage of finance, technology, communications, human resources and vulnerability to be closed.

In recent years the study of various costing pattern, led to revealing deficiencies for that and trying to improve them. However, because of the importance of cost and the advantage that recognizing it has in planning and rating of organizations, in this research has been tried to assessment of function of Time Driven Activity Based Costing (TDABC) pattern, compared to the classical costing in particular ABC, in service companies. This paper has an applied purpose and the analysis is descriptive by using correlation method. Financial records and documents were used to the collecting the data and finally the costs calculated by TDABC model and current model, then Student's t-test were used to compare the two samples. The results indicated that TDABC was more efficient than the classic costing, which used at Barakatel Company, for calculating the service's costs. This method can also apply by managers to finding out the idle capacities and costs for different purposes.
